1. MICHELIN PROPOSES A NEW A319/A320/A321 NLG TYRE
30x8.8R15 - P/N M NZG Design

2. 30x8.8R15 P/N M08201 / P/N M08202 COMPARISON
M M08202 Max tyre weight 22 kg 20 kg
Avg tyre weight 21 kg kg
Number of grooves Tread skid depth in in
Tread performance Base 100 120 Retreadability Unchanged
M08202 has been designed to be mixable with current M08201

3. Why NZG ?
Provide the Airlines benefit from a reduced maintenance cost due to increased LPT performance.
Provide the Airframers benefit from the latest radial tyre technology .
Introduce more reliable products for the aircraft industry.

4. What is NZG ??
Our R&D Efforts have developed a new Reinforcing Material :
Higher Modulus than Nylon Growth limited to less than 3%)
Modulus stable with temperature (Maintains geometry at high temperature)
Adhesion to rubber maintained up to high temperatures
Resist to cyclic fatigue

Working Point when Tyre Inflated at nominal pressure
“NZG” Casing and Belt Plies are made of much higher modulus cords

6. “NZG” TECHNOLOGY
The reduced elongation provides :
Better resistance to abrasion for optimum landings per tread
Better resistance to tear and cuts for a reduction of early removals and increased average landings per tread
Better tread and sidewall resistance to ozone attack & aging

7. “NZG” TECHNOLOGY
Reduced elongation : Before inflation the NZG tyre is larger than the current tyre.

40 mm (1.6 in)

8. “NZG” TECHNOLOGY
But, when inflated and loaded, nylon and NZG tyres have similar outside diameter, and, particularly, identical loaded radius and rolling radius

9. “NZG” TECHNOLOGY Moreover, tyre footprints are similar New M08202

10. “NZG” TECHNOLOGY
Reduced elongation : The normal initial 12 H stretch period can be reduced to 1 hour (the 24 H pressure check remains)
